What about the men who were living dangerously by assaulting women? What do you think men were protecting women from? If you're going to talk about war, you have to talk about offense as well as defense, and some significant percentage of warriors were injured/killed while attacking, not defending, and then the survivors went on to rape and pillage. Some of these men were taking resources, not protecting them. For some men to be "protectors" means others are aggressors. If men lead more dangerous lives due to war and violence, you've got to consider how much of that danger they created themselves.

"Protection" that involves attacking others first is pretty questionable from a moral and practical standpoint. "No first strike" policies for nuclear weapons, for instance, would go a long way to making the world safer.
